The first antibiotics were licensed for use in animal feed in 1948. This came shortly after World War II, and they were quickly discovered to prevent illness in commercial chicken houses. With these discoveries, farmers could grow more chickens in a tighter area and, most importantly (to them) faster. This was one of the first steps in commercializing the entire farming system in the USA.

Without knowing the long-term effects, farmers, alongside large-scale meat contractors, began using antibiotics in all production areas. From dairy to poultry, antibiotics soon took over big AG.

Today, I want to discuss antibiotics and their connection to meat. (and why you should say NO!)

In conventional farms, all types of livestock are given antibiotics to protect them from illness. On most farms, animals are often treated as needed. However, some farms use a blanket approach that treats both sick and healthy animals.

Drug manufacturers require all animals that have received antibiotics to undergo a strict withdrawal period to ensure the antibiotics are expelled from the animal and reach a “safe” level before their products are deemed fit for consumption. Leaving only a trace of antibiotic residue for us humans to process.

So, what’s the problem with antibiotics in meat?

First and foremost, we remain uncertain about the long-term effects of these trace levels of antibiotics in meat and their impact on humans who ingest it daily.

Antibiotic resistance is a major concern today, arising from people eating the products themselves and resistant bacteria entering our environment. This happens when the bacteria in the animal becomes resistant to the antibiotic given and then leaves the animal through its feces, urine, or saliva. These newly resistant bacteria can then be transmitted to us humans through the air, water, or even our food!

Another problem with antibiotics (and in my opinion, the most important) is the quality of the final product. Broad-spectrum antibiotics commonly used can injure or kill the different types of microbiology in an animal. This means the essential microbes in an animal's gut can be almost entirely wiped out by the antibiotic, critically affecting the animal's ability to digest and capture nutrients from the feed.

Animals raised in a system using antibiotics often reach their marketable weight faster; however, without the essential gut microbes, their meat and other products are significantly less nutrient-dense than their natural counterparts.

Finally, farming practices and animal quality of life are significant concerns regarding antibiotic use. Many people think that by not giving animals antibiotics, farms are creating poor environments and not properly caring for their animals. That’s simply not true.

Farmers who avoid using antibiotics in their livestock, like us, must take proactive steps to prevent their animals from falling ill. However, as you know, we do not live in a perfect world and animals do get sick. If we encounter the rare sick animal on our farm, we will give them the proper treatment to get them back to health. The animal is then culled from our herd and sold to another farmer.

To limit and some years even eliminate the need to remove animals from our herd, we employ practices such as pasture raising, daily movements, and a careful monitoring system to ensure our animals can fight off any harmful bacteria that may come their way.

Keeping the livestock out in the pasture gives them access to sunshine, fresh air, and nutrient-rich feed. This helps them naturally boost their immune system and in turn, significantly limits the chances of the animals getting sick.

Moving the herd daily helps prevent the spread of harmful bacteria. After a section of land is grazed, it will not see animals for at least another two to three months, providing ample time for recovery. Besides healing the land, these daily moves allow us to observe each animal as it passes by, allowing us to closely monitor the herd's health.

In closing, there are many drawbacks to eating products from animals raised with antibiotics. For better animal welfare, a guaranteed antibiotic-free product, and a higher nutrient density -

PCOS Medication for Chickens?

While scrolling through one of my subscribed bi-weekly AG E-Newsletters, a headline caught my eye - “Chicken or the egg (or the drug)? - Research shows that a common diabetes medication for humans (metformin) can help broiler breeder hens produce more eggs.” I was sitting across from my brother John, and words came out of my mouth that resembled something like, “What in the world are they giving to our chickens now?!?” As he is subscribed to the same newsletter and is a little more organized than I am, he already read the article; he just smirked. Once I finished reading the article, we discussed whether we thought this was a good idea or not; you can probably guess our opinions. In summary, the article says researchers at Penn State have discovered that metformin, a medication commonly used to treat type 2 diabetes and polycystic ovary syndrome (PCOS) in humans, can significantly enhance egg production in broiler breeder hens. In a 40-week study, hens administered a small daily dose of metformin laid more fertile eggs, showed reduced body fat, and showed healthier reproductive hormone levels than untreated hens. The study revealed that metformin influences liver gene activity, increasing the production of yolk proteins and stabilizing blood sugar levels while decreasing genes associated with fat accumulation. These effects mirror metformin's action in humans, where it improves insulin sensitivity and hormonal balance. Penn State This research suggests that metformin could be a tool in poultry farming, potentially extending the productive laying period of hens, reducing flock turnover, and enhancing overall farm efficiency. Significantly, metformin is rapidly metabolized in hens, thus they claim, minimizing any risk to the food supply. (Here’s a link to the full article) If you read the article closely, you can see that this medication is NOT being used and has yet to enter our food system. However, it is a good example of how the American ag industry can create its own problem and solve it by throwing a drug or chemical at it. Let me put this in simpler terms and use the example of Metformin in chicken production. How Big Ag Views the Dilemma Problem: Broiler Chickens do not lay enough eggs, and we can make more money if they lay longer and more fertile eggs. (It will take fewer momma chickens) Solution: Give chickens drugs that affect their hormones, enhancing their egg-laying abilities. Here’s How We View the Dilemma Problem: Broiler Chickens do not lay enough eggs, and we can make more money if they lay longer and more fertile eggs. Solution: Don’t grow chickens unnaturally fast! The issue is that we’ve bred our livestock and crops to grow so fast and so large for the sake of “efficiency” that we’ve become too reliant on drugs and chemicals to keep up with this fast-paced farming method. Chickens, for instance, used to take 16-20 weeks to reach their market weight; now, they are bred to reach market weight in about 6 weeks! This rapid development causes the chickens to grow unnaturally fast, which has significant side effects for both the chicken and the person. Things have developed too far for the case of efficiency in our food system. Statements like this tend to give rise to many arguments, mainly along the lines of There are not enough farmers to produce all of the food.It’s not good for the animals to be out in the open without antibiotics.We can’t grow enough food to feed the world. 1) There are not enough farmers to produce all of the food - Let’s start by looking at the farmers. In 1776, 90-95% of Americans were farmers. They grew all of the food they needed to survive. Most people had their own garden or small livestock herd. Now, around 1.3% of the population in America are farmers, with the number declining every day. So, how did we get here? Once cities and populations began to grow, it became increasingly desirable for people to hone in on one skill and trade it with others to make the community thrive. (For example, blacksmith, cobbler, preacher, builder, farmer) Most people traded their services and goods within 10 miles of where they lived. This built strong community ties and a willingness to work together. Eventually, the Industrial Revolution came along and built faster transport, better equipment, and communication. Businesses could trade their goods over a farther distance. This new ability to market to larger numbers of people started the corporatization of the American Farm. Farming became more efficient after World War 2 with the use of chemicals, tractors, and bigger equipment, which meant that those who were the best marketers, and could sell the most, had the most money to buy new farms and plant more crops. They could afford to buy up bigger and better equipment and land, and in turn, could grow more food cheaply. This caused prices to drop, and the little farmers could not keep up. If we exclude the less than 10-acre farms (which are still vital but don’t make up for a large portion of food eaten in America), we can see that in 1920 the average farm size was 148 acres, whereas in 2022 the average size was 1500 acres! A 1000% increase in size! This shows the devastating number of farms and farming families forced to shut down their tractors to make room for these big farms. To grow food in a more natural way, we would need more farmers, each with a common goal to feed the world with good food. 2) It’s not good for the animals to be out in the open without antibiotics We will not spend much time on the next argument, which is that it’s inhumane for animals to be raised without the use of antibiotics and drugs. I somewhat agree with this argument. Let me explain. It would be inhumane for us to raise animals in a confinement system without the use of these drugs. All of the animals would be sick and more than likely die, simply because they were not designed to be grown in this manner. At Red Hill Harvest, we believe that God designed animals to be raised outdoors without antibiotics or drugs. When raised in the pasture, there is a much lower risk of getting and sharing diseases because they are never over their manure for more than one day and do not breathe and share the same air. In the case of a confined animal operation, it might actually be more ethical to have lab-grown meat. I don’t see much difference between raising chickens in a barn, where they are kept in a very crowded environment and only fed a specific ration of feed (not free choice), and in a “lab” where the meat is being manufactured. 3) We can’t grow enough food to feed the world. The final argument that we will not be able to grow enough food is simply untrue. Many farms, especially where we live, simply are not suited to have crops grown on them. Rather than increasing a subpar crop of corn and soybeans, we could grow a bountiful crop of grass and other high-quality forages and walk the animals to the feed. (You would also eliminate the need for heavy machinery and help the environment tremendously.) How much sense does it make for us to grow feed, harvest it, truck it, store it, re-truck it, grind it, haul it back to the farm, and finally feed it to an animal? We recently bought a piece of land that was about 60 acres in total. On the sale bill, it said 40 acres were tillable and around 20 acres were wooded. Really, there are about 5 acres that we consider “tillable” that would produce a decent crop. Rather than trying to grow a grain crop, we let it grow and turn into grass. Then our cows can walk across the steep hills and valleys without causing harm to our machinery or the land. This way, we can utilize all 60 acres (yes, we even let the cows graze the woods when it gets hot) and still produce tons of feed! Way more than we could ever grow if we were to try to plant row crops. It all comes down to the fact that there are no longer enough farmers. Feeding the animals right off the land requires more management and labor to set up fences and work with the animals. With the current number of farmers in America, it would be challenging to scale back to a manageable size. How can we solve the problems in our food system? I believe it would be very difficult to emerge from the hole we have dug as a society. Farms are controlled by so few people that it would be hard to attract new farmers and start more farms. It would mean promoting and helping new farmers buy land, meaning the large corporations would have to dissolve. I don’t know what you think, but I don’t see that happening without significantly disrupting our food system. You CAN make a difference, however. You can control how your food is produced by choosing where you source your food. A growing number of people are fed up with the current food system and how things are being raised. Things will change if we all join together and make smart decisions in choosing where we source our food. While there are many promising things happening at the government level to promote healthy and sustainable farming practices, it’s not enough. If we reject food from the corporate world, and support small farms and farmers who raise their products the way you want them to, we can make a change. I hope that the last paragraph encouraged you to start making a difference. Money controls politicians and businessmen alike, and where you choose to spend it will shape the course of our future. With the developments of social media and websites, you can see exactly how your food is produced without even setting foot on a farm! You can reconnect with your farmer, reject the highly industrialized, unethical farming method, and support a farm that wants to support your health!

Tariffs: How they will affect meat prices, our farm, and how you can protect yourself from higher prices!

Lately, we’ve had folks asking how tariffs might affect meat prices and what that means for our farm. The short answer? Tariffs could raise costs across the board—from feed and fertilizer to equipment and meat itself, especially in large-scale, conventional agriculture. But at Red Hill Harvest, we’re not tied to global markets the way big ag is. We’re working toward becoming 100% self-sufficient, relying on natural systems instead of imported inputs. That means healthier soil, healthier animals, and more price stability for you. We also sell directly to you, our customer—not through middlemen or commodity markets—so we can set prices based on what it actually costs to raise good food. That transparency and relationship is what helps us weather uncertainty and protect you from price swings. So what can you do? Get closer to your food. Support local farms. Ask questions. Visit. Build relationships. When you choose to buy from people who care, you’re investing in a better, more secure food system for all of us.
